ABB THQLRK Series Main Breaker Retainer, 125A

The ABB THQLRK Series Main Breaker Retainer is a 125A-rated retainer engineered to secure THQL main breakers in ABB PowerMark Gold load centers. This retainer is offered across a range of compatible load center configurations spanning 6-42 circuit panels up through 12-42 circuit panels, giving electricians a flexible retention solution for the specific panel they are servicing. Depending on the configuration selected, the retainer either preserves usable breaker positions or occupies a single breaker space in the load center, so it's important to match the correct option to the panel on the job. In all configurations, the THQLRK retainer holds the main breaker firmly and securely in place for a reliable, code-compliant installation.

Key Features

  • Amperage Rating: 125A retainer rating engineered for compatible main breaker applications.
  • Load Center Range: Available for 6-42 circuit PowerMark Gold load centers (no breaker space used) and 12-42 circuit load centers (occupies a breaker space), covering a wide span of panel sizes.
  • Application: Designed for PowerMark Gold load centers using THQL main breakers.
  • Alternate Use: Also suitable for main lug load centers utilizing a back-fed branch breaker as a main.
  • Space-Saving Option: The 6-42 circuit configuration does not occupy a breaker space in the load center, preserving usable circuit positions, unlike the THQLRK1.
  • Secure Retention: Holds the main breaker firmly in position within the load center for dependable, long-term performance across all supported configurations.
  • Packaging: Supplied 1 EA per package for straightforward stocking and installation on service calls.

Technical Specifications

  • Amperage Rating: 125A
  • Load Center Circuit Range / Breaker Space Usage: 6-42 Circuit Panels '' No Breaker Space Used; 12-42 Circuit Panels '' Occupies a Breaker Space

Typical Applications

  • PowerMark Gold 6-42 and 12-42 Circuit Load Centers
  • THQL Main Breaker Retention
  • Main Lug Load Centers with Back-Fed Branch Breaker as Main
  • Residential and Light Commercial Panelboard Servicing

ABB THQLRK1 – Frequently Asked Questions

1) What's the difference between the ABB THQLRK1 and THQLRK4 breaker retainers?
Both are 125A main breaker retainers, but they differ in panel range and whether they cost you a circuit position. The THQLRK1 is for 12-42 circuit panels and occupies a breaker space. The THQLRK4 covers 6-42 circuit panels and uses no breaker space, so you keep every usable circuit position in the load center. If your panel is already full or close to it, the THQLRK4 is the one to order.
2) Will the ABB THQLRK retainer work in a PowerMark Gold load center?
Yes. The THQLRK Series retainer is made for PowerMark Gold 6-42 circuit load centers running a THQL main breaker. That's the primary application, and it's where the retainer seats and holds the main in position.
3) Do I need a breaker retainer if I'm back-feeding a branch breaker as the main in a main lug panel?
That's exactly the second application for the THQLRK retainer. Beyond PowerMark Gold panels with a THQL main, it's also intended for main lug load centers where a back-fed branch breaker serves as the main, holding that breaker mechanically in place so it can't be removed while energized.
4) My panel is a 6-circuit load center. Which ABB retainer do I order?
The THQLRK4. It covers 6 through 42 circuit panels. The THQLRK1 version starts at 12 circuits, so it won't be the right call on a small 6 or 8 circuit load center.
5) Will adding a main breaker retainer cost me a circuit space in the panel?
Depends which one you pick. The THQLRK4 does not take up a breaker space, so all circuit positions stay usable. The THQLRK1 does occupy a space, which matters on a panel that's already at capacity during a retrofit.
6) Does the ABB THQLRK retainer fit THQL breakers specifically?
The retainer is built around THQL main breakers in PowerMark Gold panels. It is a breaker-specific retention kit, not a universal clip, so match it to a THQL breaker in a compatible load center rather than trying it on another breaker family.
7) Is the 125A rating on the THQLRK retainer a limit on the main breaker size?
The retainer carries a 125A rating, so it's matched to main breaker applications at that level. It's a mechanical retention part, not a current-carrying device, but the rating is what tells you it belongs on a 125A-class main rather than a larger service.
8) How many retainers come in a pack of the ABB THQLRK?
One each per package. That suits truck stock for a service call or a single panel upgrade; order per panel if you're standardizing a portfolio of units.
